"j f4 Claims. ivry invention relates to a Ynew `and useful lei. 2i-216)Vv Vprevent, the plastic improvement'in snap fasteners, and in its-broadest aspect is similar 'to the `snap' fastener illustrated and described byome infPatent No.12,'256,

1 V35), of September` 23, 1941,V entitled VSnap fasltenersfi f In the patent above mentioned, the socket member was provided with prongs which in turn were engaged and held by a ring member, which ring memberin turn Wasin'serted inaplastic that -formed the head Yof,i,l1e`ring member.' The plastic provideda pleasing appearance inasmuch as it `Was chosen to harmonize. with. the garment- Yto which the shapfastenervvas attached. Y One-of the objects of the present inventonls somewhat simplify the construction, andp'roa4 Vide a ring prong member which isprovidedfwith a plastic face or covering, which prongamember, in

turn-israssociated Withthe socket member. Another object otithe invention' is to provide sists oi a metalfrimV thatis 'slightly curved. or dished, while fromthe inner periphery of therim extends the prongs. surface of thering meinberand forming 'an arch `or dome-shaped'faceds a1 plastic-of the' desired.

on argreatly enlarged'scale WhatI term the prong provided it has a central hub to receive the studY or male member of the fastener, and also has an outwardly Vextending curled rim to receive the prongs of the prong member. Still-another object of the'invention is to provide the socket'mem'ber, together with the prong member, the prong member having a plastic insert and last throughout secured to the socket member when'the Vvfastener isattached to the cloth; and second', the 'prongs form a plurality of anchoring points for me plastid iiller that is used as the facev of the prong member.

the ring member, not only doesthering member (slightly arcuatev in cross section) act as acharnber in which the edge of the plastic is set, but also Thus when the plastic is embeddedo'r molded to theplastic ilovving around the upper'ends ofthe plurality off prongs will be Well Vanchored fand First-and most important, 3

member I, which is in the'form of'a'r'ing preferably formed of brass, the ring beingfslightly-arcuate as at 2, while spaced around the inner periph- Y ".eryof the ring there is ,provided ay plurality of prongs `3, which, in turn, 'are to ring member'i. (See Fig. 5.) v Referringnow more particularly to Fig. 2,' it will be seen that there is provided a plastic face 5, Y Which may be a urea-formaldehyde composition, such as Plaskon, and may be be received by a lucent, or even' opaque, and may be of any desired or face which when once molded about Vthe ring `plastic having if desired insigniaor a designmight be molded in As is Well known, the plastics that have the characteristic of high flovvrwill color, preferably,

reproduce with great fidelity the engraving in the v mold or die cavity in which Yrim 2, as maybe seen at the It will Valso be noted in Fig; 2, that the ,plastic composition ivvilljbe well anchored beneath the point 6. Y't will also be seen that Ythe. plastic during the molding 013- 'eration will flow about the proximal ends of the multiplicityV of prongs 3, so that after the plastic once. hardens or sets,.itV Will never loosen or b'ecomedetached fromits prong fastener ring land 2,V there` is shown transparent, transthe plasticis molded. Y

' Also by-forming the plastic face S slightly arcuate in cross section, the cloth material 'E Where'V it passes under the ring vand the plastic, willinct i become jammed or injured duringthe attaching Operation. Y Y i l l' jr. Y Y

t might be mentioned that Whehthew'prongv member .ris attached-to the socket' niemberythie face ofthe plunger ordle ofthe attaching ma: chine AWill also be slightly concave, so that thev pressure will be exerted uponfthe 1ring, rather than on the dome of the plastic. Y f

Referring now briefly to the socket member fas shown in Figs. 4 and 5, it might be mentioned that this may be of any desired construction, providing it WillreceiveV the prongs ci the ringmember, andof course, receive the stud or male mem- Y ber of the fastener. f
